Float Switch For Industry Pump Tank Sensor 

A float switch is a mechanical liquid-level sensing device used to automatically control pumps, alarms, or valves based on the liquid level in a tank or sump. It works using a sealed float containing an internal microswitch that changes state when the float tilts due to rising or falling liquid levels. This makes it a simple, reliable, and cost-effective solution for liquid level control in industrial and domestic systems.
